IBM is not ready to guarantee that its computer programs are compatible with Oracle's recently launched version of the Linux operating system, an IBM spokesman said on Friday. This means that if IBM software programs turn out to be incompatible with Oracle Enterprise Linux, then it will be up to Oracle - and not IBM - to resolve the issue, said IBM spokesman Matthew McMahon.

It's not "Oracle's RHEL", it is based on it. What tweaks did they have to do to improve it over RHEL if any? I am a bit leery about it since I know RH has lots of devs that have worked on Linux, can Oracle match their experience and skill with the OS? Will Oracle certify their database for CentOS?
